Having trouble tuning this #28

Open lukepighetti opened 1 year ago

lukepighetti commented 1 year ago

I am trying to control a wood stove. Set point is 300°f. Damper control is from 0% to 100% open.

If the temp is 305° and the set point is 300°, I expect the damper to be approximately 40%. No matter how I change p it always goes to 0%. It's very aggressive.

Any suggestions?

Temp Expected damper opening
290 70%
295 60%
300 50%
305 40%
310 30%

I recognize that we cannot control the stove simply with this table, but it should NOT be swinging from 0% to 100% when it's only 5° off. We need it to taper in and out slowly.

Best I've been able to come up with is make it a bang bang by setting the low/high and adjusting it as needed
